• B. Structure boundary
• C. Structure line

Answer: A

Explanation:
Structure junctions support domain features such as transformers, typically modeled as poles or towers.

NEW QUESTION # 28
When validation rules are evaluated in ArcGIS Utility Network, where are data violations stored and tracked?

• B. Network attribute tables
• C. Error datasets

Answer: C

Explanation:
Violations are logged inerror datasets, which allow users to identify and fix invalid data.

NEW QUESTION # 29
In ArcGIS Utility Network, which property is derived from feature class attributes, cached in the topology, and used to speed up tracing and analysis?

• A. Subnetwork controllers
• B. Network attributes
• C. Asset types

Answer: B

Explanation:
Network attributesare cached to make tracing and subnetwork evaluation more efficient.

NEW QUESTION # 30
What is the key difference between a domain network and a structure network in ArcGIS Utility Network?

• A. Structure networks enforce connectivity, while domain networks enforce containment
• B. Domain networks define ranks, while structure networks manage terminal paths
• C. Domain networks carry resources, while structure networks provide support

Answer: C

Explanation:
Domain networks model theflow of resources(e.g., water, electricity), while structure networks provide physical support.

NEW QUESTION # 31
When setting up a utility network, which of the following describes the main function of terminals in modeling flow?

• A. Provide attachment points for domain features to structures
• B. Act as subnetwork controllers and define valid flow paths through devices
• C. Enforce containment rules for assets

Answer: B

Explanation:
Terminals model how resources enter/exit devices and act as controllers to define subnetwork origins.

NEW QUESTION # 32
When configuring a partitioned tier definition in ArcGIS Utility Network, what type of terminal configuration must be used to properly define flow direction?

• A. Directional
• B. Single Terminal
• C. Bidirectional

Answer: A

Explanation:
Partitioned tiers requiredirectional terminals, since they model sequential flow from higher to lower tiers.

NEW QUESTION # 33
A field technician is using ArcGIS Field Maps with a published utility network. Which two actions are supported in Field Maps when interacting with the network?

• A. Offline editing and schema changes
• B. View associations and perform traces
• C. Apply validation rules and create subnetworks

Answer: B

Explanation:
In Field Maps, users canview associationsandrun traces. Offline editing workflows are not supported.

NEW QUESTION # 34
A technician wants to quickly add a standard arrangement of devices such as arresters, fuses, and transformers with a single placement action. Which type of template should be used?

• A. Group template
• B. Preset template
• C. Containment template

Answer: B

Explanation:
Preset templatesplace a fixed pattern of features in one step, ideal for standard device arrangements.

NEW QUESTION # 35
When configuring valves or switches in ArcGIS Utility Network, are terminals necessary if both sides of the device are equal?

• A. No, terminals are only required if the device is a subnetwork controller
• B. No, terminals are only required when sides differ, multiple ports exist, or flow is directional
• C. Yes, all devices must have terminals

Answer: B

Explanation:
If both sides of a device are identical, terminals are unnecessary. Terminals are used when sides differ or multiple ports exist.

NEW QUESTION # 36
A GIS administrator must decide between different deployment options for ArcGIS Utility Network. Which of the following correctly describes the two supported deployment types?

• B. Cloud deployment vs. on-premise deployment
• C. Partitioned deployment vs. hierarchical deployment

Answer: A

Explanation:
Single-user deployments exist in file geodatabases. Multi-user deployments require enterprise geodatabases with branch versioning.

NEW QUESTION # 37
An analyst encounters error code 36: "Line feature has invalid terminal." What does this error indicate, and how can it be resolved?

• A. Line's terminal fields are invalid; fix by setting the correct terminal or clearing invalid values
• B. The containment rule is missing; fix by creating a containment association
• C. The line feature overlaps another; fix by merging lines

Answer: A

Explanation:
This error means the From/To terminal fields on the line are invalid or mismatched. Fix using theTerminal Connections toolor by resetting terminal fields.

• B. All subnetworks are updated regardless of edits
• C. The tool deletes subnetwork controllers before updating

Answer: A

Explanation:
Whenevents are enabled, the tool updates only those features that have been edited, improving efficiency.
